SYLVANIA A19 ULTRA LED Light Bulb, 12W, 75W Equivalent, 13 Year, Dimmable, 1100 Lumens, 2700K, Soft White - 4 Pack (74425)

I'm a lighting enthusiast and lamp collector. Like, my living room has 19 lamps in it; and a few fixtures too. No, I don't turn them on all at once. I create a mood by switching it up. Anyway, since I'm a light bulb hog, I was a very early adopter of LED bulbs because they do slash a power bill for a super user like me. And I'm on to my 2nd and even 3rd gen with LEDs because I've truly used them for 50K hours. But I digress. These are significantly brighter than the bulbs of "equal" lumens they replaced. No complaints there because I can, and do, dim them for ambiance. Perfectly warm light, in that pleasing 2700-3K temp--I never use those bluer light temp bulbs. When I started out with LEDs, I spent top dollar on famous name brands. I wanted the best product. At this point in the evolution of LEDS, it was nice to find a good brand at such bargain-type price. So I'm perfectly satisfied and highly recommend the Sylvanias at this point. As for longevity, call me in five years.

Received these Sylvania 16 Watt, 2700K (warm white) screw in bulbs, and I was pleasantly surprised that they have a smaller diameter than other 16 Watt bulbs. They measure 60mm/2.35" in diameter while the other (non Sylvania) 16 Watt bulbs I've bought in the past measure 70mm/2.75" diameter. The difference in diameter allows me to get a glass globe over a new bulb in a hallway fixture. They definitely appear to be 2700 K color temp, and I can only assume the brightness reaches their rated 1600 lumens. They seem bright.

I went through many cheap brands of led lights that fail in a year or less. The common theme with the cheap bulbs is they don’t handle the generated heat well. I switch to these as I was tired of changing the cheap ones that die way too fast. So far I have not had one of these fail. I will happily pay more for a produce that will far outlast other products.

So you want to know what these look like right? Go outside at 12 Noon on a clear day and look at white piece of paper, now you know. I tried the 3000K Hyperikon and they are wonderful with a high CRI (90+) so the colors just pop. I tried the 4000K which put out a dirty yellow color that I am not fond of at all.I tried the 5000K which are OK for the Kitchen or Garage but not for a Bedroom. These 3500K Bulbs are for people who don't like the other Color Temperatures like me, it's a Neutral Color. The CRI is only 80 but it looks OK. If you didn't know, a low CRI will make things look dull.I'm quite sensitive to light with Headaches etc and I can tell you that these do not flicker or give me a Headache. In case you are wondering, a CFL has a CRI of 80 tops. LEDs can go up to 95 currently and I wish they would all switch to a high CRI for the consumers sake.I think these would be nearly perfect with a CRI of 90. So I hope this review helps you if you're not sure. The Color is that of the Sun on your Arm at Noon, 5000K is NOT Daylight as LED makers describe. The problem is, there is no consensus on standards yet from LED makers and these 3500K Bulbs are way too Rare.

OK - it's a light bulb. Even LED's are fairly common. I'm using these to light a screened porch. The cool-white light does an excellent job of this. I cook on a black-colored griddle and cooking in dim light required I wear a 'headlight' in order to see the food clearly. No more. My porch is lit like a commercial kitchen.The bulbs dim so that we can enjoy the porch without being overwhelmed with light. They do flicker a bit at the lowest settings.

I ordered a 4 pack of these bulbs which were shipped and sold by Amazon. They were exactly as advertised and worked great. I went to order another package and Amazon must have been out of stock but they were available at a lower price from Crazy Beauty. The description was exactly the same. What I received was NOT the same. The bulbs sent by Crazy Beauty were A21 bulbs not A19 bulbs, these things are HUGE and Heavy. They are not even a 4 pack, I received 4 individually packaged bulbs. I was going to return them but returning anything is a hassle and I realized that I could use them in my outside fixtures and larger lamps. They will not fit in the smaller lamps, they are larger than the harp.Note: I ordered the 1600 Lumen (100 watt equivalent) 2700K bulbs. These are hard to find at a reasonable price but my wife hates the 3000K bulbs, she says they look blue.

These look like daylight.

Éstos los compro por éste medio por el precio, en mi país son muy costosos.No tengo queja del producto y jamás se me han quebrado con el envío pese a que los pido de USA a Panamá.

je me suis fais volé avec le prix exorbitent ,et sur 4 lumiere ,2 ne son pas fonctionnel ,j,aimerais que amazon se réveil et me donne se que jai payé presque 60.00 ces pourtant assez clair se que je demande le vendeur langer pas tres ouvert d,espris merci de me lire ,et j,espere avoir de vos nouvelles bientot

Absolute garbage.....do not buy. I bought these bulbs to add more light to our family room lamps. We are currently using 9w led Noma bulbs but found it too dim. I installed these 16w (100 watt equivalent) bulbs and it didn't seem as bright as the 9w ones. Grabbed a light meter from my camera and it confirmed they are slightly darker (9w - 204, 16w - 182) Incredibly disappointing. Instead of being 75% brighter, they are 10% dimmer.

Our previous dimmable LED bulbs would not work with the new network-enabled electronic dimmer we installed. The Sylvania bulbs solved the problem, and deliver a nicer warmer light in our living room.

Los focos de calidad, buena iluminación y a buen precio

The brightness of these bulbs is just perfect for me. Not too yellow and not too blue. These were a little on the pricier side but I needed dimmer bulbs works well with my dimmer switches. Yet to see how it affects my energy bill
